Dr. Kalaysian has been my doctor for the past 4 months in the treatment of obesity. I feel that he has given me individualized attention, care, and the time I need in order to understand how to help myself. He is knowledgeable and up on the latest research. I have recommended him to several people and cannot recommend him enough.

He took care of me while in the hospital, it was the first time a doctor actually sat with me and talked to me about my diet. In the past month, I have lost over 15 pounds, following his advice and it was easy. Thank you.
